AFAIK, the only tank with an oscillating turret automatic reloading systems was French AMX-13, one of the best light tanks ever built. Much less known is that in early 1950s US Army had a numeber of tank protos built and tested. US designs were for medium and heavy tanks. I have info on three of...

Originally it was planned to be on a system like this.

This was an air defense system based on the M1 chassis. ISTR it had two 25mm guns and ADATS missiles but I can't find anything on it.

Was suppose to be a counter to the Russian JS III heavy tank. It weighed in at 65 tons with a 120mm gun. Although it did make it into service in small numbers it was a rarity.

Another interesting Hughes AAH picture - in packed form. Original specifications also called for using of ejector seats and carrying additional antitank missiles internaly, so the helicopter should be re-armed during short landing. Mi-24 crews do it sometimes.

In 1955, the US Army issued a requirement for the development of a next generation gas turbine-powered medivac helicopter The winner of this competition would be awarded to Bell with their Model 204, then designated as the XH-40, and later again in 1962 it was changed to UH-1 Iroquois. I have...

‘Retractable Skidded’ AH-1 Cobra When Bell first came up with the efficient and versatile Bell AH-1 Cobra combat helicopter design, it originally went one step further by incorporating a retractable skid arrangement. This arrangement featured the skid’s retracting into the narrow fuselage. I...

This was a design from the movie "The 6th Day," designed by Rob Cobb. Normally, wouldn't quite fit in here, being sci-fi and all... but according to an interview with Cobb, the US Army expressed interest in the design. So, you never know... This is the master model, nearing completion. Molds...

Indeed the naval "T-tail" N-156 followed the Fang in 1954, followed by the more familiar N-156F of 1956 that lead to the F-5A. I still haven't found an drawings or details on the original N-156. :(

Hi folks, I was looking for more information on the Phalanx Corporation Dragon Four-Poster VTOL concept of the 1980s (see pic below). I am also interested in some of the other concepts that Phalanx Corporation were working on including: Phalanx Dragon family of 4 poster blended...
